When the sun comes up, the gazelle wakes up knowing that it must outrun the fastest lion or it will be eaten. The lion knows it must outrun the slowest gazelle or it will starve to death. So it doesn't matter if you are a gazelle or a lion, when the sun comes up, you had better be running. --An African proverb.

If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son.
--Excerpt from "If" by Rudyard Kipling

"So many people live within unhappy circumstances and yet will not take the initiative to change their situation because they are conditioned to a life of security, conformity, and conservatism, all of which appear to give one peace of mind, but in reality nothing is more damaging to the adventurous spirit within a man than a secure future. The very basic core of a man's living spirit is his passion for adventure. The joy of life comes from our encounters with new experiences..." -Chistopher McCandless
